Your car is a 2001 - Do both sway bushes & links + castor bushes if they have not been done in the last 30,000 miles.

Since they will be replaced with updated parts, how long will they last until they need replacing again?
Do i have to lubricate anything while im under there?

No lubrication required - Sways & links will last a long time totally dependent on use. If you hit a pothole really hard you can damage a link end in in one bang. But I mean a real rim bender.
Castor bushes will remain a weakness - just watch them for cracks & leaks. Mine were heavily cracked at 30,000 miles - never leaked - new ones have little mileage on them & so far OK. Dealers say leave them in until alignment or noise becomes an issue. I say no way - why mess up tyres. New ones are softer rubber but still fail.

My mechanic says the suspension components last around 80k miles before they go bad and by then (from his experience) people usually sell their car by then and dont worry about it. Hopefully this will be my last time changing them out as im guessing they will go for another 70k miles or so and by then i will have sold my car.
I know what you mean from bushings, it seems like these are a real weakness on these cars, i mean my strut bearings were severely cracked and leaked like crazy.

Glyn, old mate, What causes the problem , bad design, poor materials ? Crickey, my old 504 Peugeot went for 300,000 km before any front end bushes had to be changed. Our Peugeot 405 has done nearly 300,000 & the front end is still as tight as a drum.
I am not looking forward to changing these out every 30,000 on my new C Class which is supposed to have been tested for millions of Km !! !! Not happy John.!!

Hi John - German paranoia with NVH - They look simple externally but are in fact a fairly complex silicone fluid filled bush or bearing as Benz call them.
It's a design & materials issue - They have been redesigned & made 12% softer but still give trouble. It seems less of an issue on W204s but still there.
It all started with Benz having to put out this bulletin - ignore VIN numbers - it applies to all W203 - it's been ongoing since then. They are large bushes & it amazes me the way they fail. If it was a solid bush I'm sure it would not but then we might feel a little more vibration.

Read this thread where I discuss once of numerous times - It's also under the W203 stickies DIY - castor/crash bolts etc.
